Over the last decade, avian influenza (AI) has been considered an emerging disease that would become next pandemic, particularly in countries like South Korea, with continuous animal outbreaks. In this situation, risk assessment is highly needed to prevent and prepare for human infection AI. Thus, we developed matrix a high-risk area of AI Korea based on notion multiplication hazards vulnerabil...
greater levels of complexity in tunnelling with tunnel boring machine (tbm) allow higher chances of failures that may increase the potential hazardous risks. this paper presents the results of a study on tbm reliability using risk analysis. machinery failure mode and effect analysis was applied to analyze the risks of a tbm using qs9000 and sae.j1739 recommendations. for this purpose, 48 failur...
analysis of time series data can involve the inversion of large covariance matrices. for theclass of arma (p, q) processes there are no exact explicit expressions for these inverses, except for thema (1) process. in practice, the sample covariance matrix can be very large and inversion can becomputationally time consuming and so approximate explicit expressions for the inverse are desirable.thi...
Background; Prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. The purpose of this study was to compare the ETBA and HAZOP techniques for risk assessment in a gasoline refinery unit. Methods; In this case study, data were collected using process flow diagram, walking–talking through method, piping and instrument...
Introduction: Identifying occupational hazards and managing occupational safety and health risks is the most important mission and responsibility of the health and safety management system in organizations and adopting coded plans to achieve this is the key to continuously improving this system and promoting it. Method: This descriptive-analytic research has been written to determine the optim...
Background: Type 2 diabetes is the most common type of diabetes, and a complex endocrine metabolic disorder that one of its main complications is diabetic foot ulcers. Matrix metalloproteinases (MMPs) are one of the key enzymes in the reconstruction of extracellular matrix which have proteolytic activity. The aim of this research is based on evaluating relationship between -1562 C>T allele at M...
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Background and aims: correspondence analysis method and preparation of accident and occupational hazards pattern enables forecasts and predictions of accidents and prioritizations of risks and injuries to be obtained automatically. The procedure for any company, regardless of its size is applicable. This study presents the first model accidents and occupational hazards as a first step to identi...
